What's new in CubicWeb 3.16?

Add a new dataimport store (SQLGenObjectStore). This store enables a fast
import of data (entity creation, link creation) in CubicWeb, by directly
flushing information in SQL. This may only be used with PostgreSQL, as it
requires the 'COPY FROM' command.

Dropped 'pyro-ns-host', 'pyro-instance-id', 'pyro-ns-group' from the client side
configuration, in favor of 'repository-uri'. NO MIGRATION IS DONE,
supposing there is no web-only configuration in the wild.

Stop discovering the connection method through repo_method class attribute
of the configuration, varying according to the configuration class. This is
a first step on the way to a simpler configuration handling.

DB-API related changes:

Stop indicating the connection method using ConnectionProperties.

Drop _cnxtype attribute from Connection and cnxtype from
Session. The former is replaced by a is_repo_in_memory property
and the later is totaly useless.

Turn repo_connect into _repo_connect to mark it as a private function.

Deprecate in_memory_cnx which becomes useless, use _repo_connect instead
if necessary.

the "tcp://" uri scheme used for ZMQ
communications (in a way reminiscent of Pyro) is now named
"zmqpickle-tcp://", so as to make room for future zmq-based lightweight
communications (without python objects pickling).

The RQL search bar has now some auto-completion support. It means
relation types or entity types can be suggested while typing. It is
an awesome improvement over the current behaviour !

The action box associated with table views (from tableview.py)
has been transformed into a nice-looking series of small tabs; it
means that the possible actions are immediately visible and need not
be discovered by clicking on an almost invisible icon on the upper
right.

The uicfg module has moved to web/views/ and ui configuration
objects are now selectable. This will reduce the amount of
subclassing and whole methods replacement usually needed to
customize the ui behaviour in many cases.
